PURPOSE: A transponder device supporting high speed roaming in a wireless LAN mesh network is provided to supply various additional services by continuously receiving high speed data while driving. CONSTITUTION: A terminal device(320) moving at high speed communicates with a wireless mesh AP(300). The channel switching speed of the wireless mesh AP connected with the portable terminal device is determined by the period of high speed roaming channel and a channel search range. The wireless mesh network communicates routing information between APs and a high speed routing mode is determined by the channel period. The wireless mesh AP connected to the terminal device estimates the number of terminal devices connected to the wireless mesh AP, traffic usage, and communication delay time and determines an optimum roaming channel. |
